How To Clean Drain Hole At Back Of Fridge Hot!

Modern frost-free refrigerators cycle a heating element to melt ice off the evaporator coils. The resulting water flows via gravity to a drain hole at the back of the fridge, through a flexible hose, and into an external drip pan where it evaporates. Blockage of this drain hole—by food debris, coagulated fats, or biofilm—causes standing water, freezing in the drain line (creating an ice plug), and eventual water leakage onto the kitchen floor.
